As I was walking down to Bayfront Park to watch the Le Festival des Montgolfières I noticed a lot of fog. As I neared the harbor I could hear a fog horn but it was not coming from the lighthouse. It turned out to be the Baie St Paul which was sitting out in the harbor blowing its fog horn. Apparently the fog was too thick for it to try and navigate the Ship Canal so it was sitting and waiting for the fog to clear. It was about a half an hour before it was able to navigate the Ship Canal.
